I seated myself (я усадил себя = сел) in his armchair (в кресло) and warmed my hands before his crackling fire (и погрел руки перед потрескивающим огнем), for a sharp frost had set in (так как сильный: «острый» мороз установился), and the windows were thick with the ice crystals (окна были густо покрыты кристаллами льда). "I suppose (полагаю)," I remarked (заметил), "that, homely as it looks (обыденная, как она выглядит = хотя она столь невзрачна), this thing has some deadly story linked on to it (эта вещь связана с какой-нибудь кровавой историей: «имеет какую-то смертельную историю, связанную с этим») — that it is the clew (ключ, зацепка) which will guide you in the solution of some mystery (приведет вас к решению какой-то тайны) and the punishment of some crime (и наказанию какого-то преступления = преступника)."

"No, no. No crime (/здесь/ нет преступления)," said Sherlock Holmes, laughing (смеясь). "Only one of those whimsical little incidents (один из тех причудливых маленьких происшествий) which will happen (которые случаются) when you have four million human beings (когда четыре миллиона человеческих существ) all jostling each other within the space of a few square miles (толкают друг друга на пространстве в несколько квадратных миль). Amid the action and reaction (посреди действия и противодействия) of so dense a swarm of humanity (такого концентрированного роя человечества = в человеческом улье), every possible combination of events may be expected to take place (каждая возможная комбинация событий может произойти: «быть ожидаема, что случится»), and many a little problem will be presented (проявится множество мелких проблем) which may be striking and bizarre without being criminal (которые могут быть поразительными и странными, не являясь криминальными). We have already had experience of such (мы уже имели опыт подобного = сталкивались с такими вещами)."
"So much so (в общем-то, это так)," l remarked, "that of the last six cases which I have added to my notes (что из последних шести дел, которые я добавил к своим записям), three have been entirely free of any legal crime (три были совершенно свободны от каких-либо преступлений /по закону/)."
